Using The Bar Graph; Cleaning; Testing The Fuses - Fluke 175 User Manual

Using the Bar Graph

The bar graph is like the needle on an analog Meter. It has an >
overload indicator ( ) to the right and a polarity indicator (±) to
the left.
Because the bar graph updates about 40 times per second, which
is 10 times faster than the digital display, the bar graph is useful
for making peak and null adjustments and for observing rapidly
changing inputs.
The bar graph is disabled when measuring capacitance or
temperature. In frequency, the bar graph accurately indicates the
voltage or current up to 1 kHz.
The number of lit segments indicates the measured value and is
relative to the full-scale value of the selected range .
In the 60 V range, for example (see below), the major divisions on
the scale represent 0, 15, 30, and 60 V. An input of −30 V lights
the negative sign and the segments up to the middle of the scale.

Cleaning

Wipe the case with a damp cloth and mild detergent. Do not use
abrasives or solvents. Dirt or moisture in the terminals can affect
readings.

Testing the Fuses

To avoid electrical shock or injury, remove the test
leads and any input signals before replacing the fuse.
Test fuses as shown below.
